The water flow scouring resistance is an important performance of an automobile adhesive product, and a workpiece coated with the adhesive is subjected to bath solution soaking and clear water washing for many times before being baked and cured after being transported to a coating workshop in the actual construction process. At the moment, if the adhesive is dispersed by water flow to generate deformation, the original bonding, sealing or damping effects cannot be achieved, and adverse effects on bath solution components and bath solution filtering equipment are possibly caused. This allows the adhesive to retain its original shape in such a water flow environment, making the wash-off resistance of the adhesive itself from being flung away critical. Therefore, in order to ensure the quality of workpieces and bath solution, the water flow scouring resistance of the adhesive product is tested before the adhesive product is used.
